Abstract: A device-cloud collaboration method, platform, and apparatus, where the device-cloud collaboration method includes: obtaining current spatial information of each target terminal; tracking a spatial information change of each target terminal, to obtain a spatial information change status of each target terminal; and determining, based on spatial information-based arbitration conditions preset for different target mobile applications and the spatial information change status of the target terminal corresponding to the different target mobile applications, whether to trigger subsequent operations related to the different target mobile applications. The device-cloud platform blocks a change in which the user is not interested through arbitration of a spatial information change of the user, and provides an appropriate spatial information change to a mobile application, or triggers a subsequent operation of the mobile application.

Abstract: This application discloses a data synchronization method, where the method is applied to data synchronization between heterogeneous databases. The method includes: A terminal device records a primary key, attribute information, a version number, and a synchronization status of a data object by using a first storage format, and a cloud device records a primary key, attribute information, and a version number of a data object by using a second storage format, so that the terminal device and the cloud device implement data synchronization between the heterogeneous databases based on the storage formats and version numbers. In the technical solutions of this application, consistency in data synchronization between the heterogeneous databases may be ensured through, for example, version number management and synchronization status management.
